Hirschmann BRS20-1000M2M2-STCY99HHSEAXX.X.XX Procurement Guide: Match the Ten-Port BOBCAT -2A Configuration and Fixed 100BASE-FX Multimode Links
The full reference Hirschmann BRS20-1000M2M2-STCY99HHSEAXX.X.XX selects Hirschmann BRS20-8TX/2FX-2A, listed under part number 942170106. It is a managed, fanless DIN rail switch with eight copper Fast Ethernet ports and two fixed multimode SC fiber ports. Keep the complete ordering code in the bill of materials because another ten-port BOBCAT model can have the same connector layout but a different configuration reference.
Preserve the complete preset configuration
Do not reduce an order to BRS20 or to the eight-copper/two-fiber port count. This Type carries the -2A suffix and a product code containing SEAXX. Ask for confirmation of that exact code rather than assigning an unsupported meaning to the suffix. Any substitution should be reviewed against the project requirements and delivered-device documentation.

Commission the optical route deliberately
Both fixed optical links are 100BASE-FX MM-SC. Record whether the cable is 50/125 µm or 62.5/125 µm and verify the far-end interface, route loss and connector condition. The catalog distance references depend on fiber characteristics and optical reserve; they should not replace an assessment of the actual route being connected.
Prepare the controls team for installation
The operating range is 0 to +60 °C and the source lists two 12–24 V DC inputs. Review power/signaling wiring, management settings and port labels before changing an installed switch. The device has eight RJ45 and two optical connections in total, so document which interfaces serve local equipment and which connect to the rest of the network.
Confirm the supply scope with HKXY
Send HKXY part 942170106, product code BRS20-1000M2M2-STCY99HHSEAXX.X.XX, order quantity and destination. Include the existing configuration record or label photograph for replacements, and identify any required documents. Confirm the proposed product configuration and accessory scope in the quotation.
